A rotating shaft is arranged in the fitting cavity of the upper cover and the lower cover, and the rotating shaft forms a freely rotating state in the fitting cavity. A motor is fixedly arranged at the top of the upper cover, and the driving shaft of the motor extends downward into the upper cover and is fixedly connected to the rotating shaft to form a drive. An assembly cavity is provided on the side of the upper cover, and a micro switch is placed in the assembly cavity.
